MeshLab is an open source portable and extendible system for the processing and editing of unstructured 3D triangular meshes.
The system is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.

The project is supported by the European Network of Excellence Epoch

The system is heavily based on the VCG library developed at the Visual Computing Lab of ISTI - CNR, for all the core mesh processing tasks. The MeshLab system started as a part of the FGT course of the Computer Science department of University of Pisa and most of the code (~15k lines) of the first versions was written by a handful of students.  

Download Latest Version (22/6/2006)  V0.7 

Remember that, whenever you use MeshLab in a official/commercial project, you should feel morally obligated to:

• Explicitly cite in your work that you have used MeshLab a tool developed with the support of the Epoch NOE,
• Post a couple of lines in the users' forum describing the project where MeshLab was used.

Features

• Interactive selection and deletion of portion of the mesh. Even for large models.
• Input/output in many formats (PLY, STL, OFF, OBJ, 3DS)
• Extendible plugins based architecture, writing new mesh processing functions, colorization filters and support for different file formats is quite easy! Look at Filter-PlugIn Sample or MeshIO-PlugIn Sample
• Cleaning Filters:
  • removal of duplicated, unreferenced vertices, null faces
  • subdivision filters (midpoint, loop and butterfly)
  • coherent normal unification and flipping
• OpenGL Shader based rendering (write your own shader!) compatible with Shader Designer
• Large rendering (up to 16k x 16k) for high quality printing
• Various Colorization/inspecting Filters
  • Gaussian and mean curvature
  • Border edges
  • Non two-manifold faces
• The history of the all performed cleaning/editing actions can be re-played on different meshes or saved and for archival purposes.

Bug reports and feature requests should be filed using the sourceforge service ->
General questions can be posted on the help public forums

Snapshots taken from MeshLab v 0.7
	An interactive editing session over the a mesh built a using geometry-from-photo-sequence reconstruction tool developed withing the EPOCH framework. An unwanted part of the mesh is selected and deleted. Original mesh courtesy of the Epoch network.
	An interactive editing session over the 8M tri David model. The bottom part of the mesh is selected and deleted. Original mesh courtesy of Stanford Digital Michelangelo Project.
	One example of real time NPR rendering using a hatching style implemented through a OpenGL shader. The shader was used to create the high res snapshot (2282x2942).
Snapshots taken from MeshLab v 0.6
	A couple of examples of a OpenGL shaders applied over a 3.7 Mtri model (courtesy of Aim@Shape Shape repository)..

	A 10,000,000 face model successfully loaded and ready for inspecting. 3D Model of a Thai statue courtesy of XYZ RGB inc. provided by the Stanford 3D Scanning Repository.
	A textured ply model of the well known Michelangelo David, original mesh courtesy of Stanford Digital Michelangelo Project, texturing done by  Visual Computing Lab ISTI - CNR  through integration of photos taken during the Restoration of the David.
	A model with self intersecting faces detected by MeshLab colored in red. Mesh courtesy of the Aim@Shape  Shape Repository.
	A model with border edges colored in blue. Mesh courtesy of the  Shape Repository of Aim@Shape.
	A high resolution snapshot (4400x9110) taken with MeshLab of the 10 Mtri 3D model of the above cited Thai statuette. The snapshot is a 17Mb png, so you can download it using the sourceforge file distribution system. On the right you can see a very small portion of the orginal sample just to give you an idea of the quality of a 40 Mpix image.
	An high resolution rendering (3200x6424) taken with MeshLab of the 8 Mtri model of the Michelangelo David. Original mesh courtesy of Stanford Digital Michelangelo Project. The model is interactively rendered using a pre-computed ambient occlusion term computed with the open source ShadeVis tool. On the right you can see a very small portion of the original rendering just to give you an idea of the quality of the original 20 Mpix image.
